JSON Decoder used by runtime service.
object_hook, if specified, will be called with the result of every JSON object decoded and its return value will be used in place of the given
dict. This can be used to provide custom deserializations (e.g. to support JSON-RPC class hinting).
object_pairs_hook, if specified will be called with the result of every JSON object decoded with an ordered list of pairs. The return value of
object_pairs_hookwill be used instead of the
dict. This feature can be used to implement custom decoders. If
object_hookis also defined, the
parse_float, if specified, will be called with the string of every JSON float to be decoded. By default this is equivalent to float(num_str). This can be used to use another datatype or parser for JSON floats (e.g. decimal.Decimal).
parse_int, if specified, will be called with the string of every JSON int to be decoded. By default this is equivalent to int(num_str). This can be used to use another datatype or parser for JSON integers (e.g. float).
parse_constant, if specified, will be called with one of the following strings: -Infinity, Infinity, NaN. This can be used to raise an exception if invalid JSON numbers are encountered.
strictis false (true is the default), then control characters will be allowed inside strings. Control characters in this context are those with character codes in the 0-31 range, including
